+### pre-commit framework
+This project utilizes the [pre-commit](https://pre-commit.com/) framework to automate various small hick-ups that tend
+to happen prior to committing.
+
+To use the framework it is necessary to follow these steps:
+```bash
+# install the pre-commit hook
+pre-commit install
+
+# to test your staged files manually run
+pre-commit run
+```
